Chris Brown just arrived at court ... where the D.A. is waiting to make its case to the judge. Chris flew off the handle earlier this month while in rehab for his anger issues -- throwing objects around and breaking them -- and the rehab facility demanded he leave ... which is why CB bailed early on the program. The outburst occurred not long after Brown was arrested for felony assault in Washington D.C. after the singer allegedly attacked a man outside a hotel.
